Synthesis And Biological Activities Of Phenylsulphonylaminoalkaanamides – Complete project material

ABSTRACT Palladium catalysed synthesis of substituted 2-[acetyl(phenylsulphonyl)amino]-3-methylbutanamide (176) is reported. The intermediate 2-[acetyl(phenylsulphonyl)amino]-3-methybutanamide (175) was obtained by the reaction between 2-[acetyl (phenylsulphonyl)amino]-3-methybutanoic acid chloride (175) and ammonia. Substituted 2-[acetyl (phenylsulphonyl)amino]-3-methylbutanamides (176a-f) were obtained by coupling  2-[acetyl (phenylsulphonyl)amino]-3-methylbutanamide (175) with various readily available substituted aryl halides…

The Utility Of Suzuki-Miyaura Cross-Coupling Reaction In The Synthesis Of Angular Benzo[A]Phenothiazine And Benzo[A]Phenoxazine Derivatives And Their Anti-Microbial Screening – Complete project material

ABSTRACT   Palladium-catalysed Suziki-Miyaura cross-coupling (SMC) reactions of 6-chloro-5Hbenzo[a]phenothiazin-5-one, 11-amino-6-chloro-9-thio-5H-naphtho[2,1-b]pyrimido[5,4-e][1,4]oxazin-5-one and 6-chloro-5H-naphtho[2,1-b]pyrido[2,3-e][1,4]oxazin-5-one with phenylboronicacid and 3-nitophenylboronic acid were thoroughly investigated. The above intermediates wereprepared by the reactions of 2-aminothiophenol, 4,5-diamino-6-hydroxylpyrimidine-2-thiol and 2-aminpyridin-3-ol respectively with 2,3-dichloronaphthalene-1,4-dione…
